I sometimes get an answer to a question that has me thinking:
"This will work. But I don't like it very much. I am going to move on to something else and come back to this later and see if I have gotten a better answer."
(This question is my current example.)
Unfortunately, "later" does not always happen. I forget about the question and the user who posted a workable solution (if not as good as I wanted) did not get the credit deserved.
I would like to request the ability to put a timer on a question. Something like "In 5 days have this pop up in my StackExchange inbox."
That way I will not forget a question that has a correct answer.
This also saves me the work of going back through all my questions that do not have an answer "marked" looking for questions that fit this category.
